Microsoft’s long-rumored, dual-screen Surface device will fold up small enough to fit in a pocket, according to an internal document reported by The Verge today.

So it’s a Surface Phone? Well, yes, this mystery device has been reported to include telephony. But rather than again taking on smartphones from Apple, Samsung and Google in what has so far proven to be a losing battle, the Redmond company will reportedly position this device as creating a “new and disruptive” category.

The idea is to blur the lines between computers and smartphones, much as the original Surface blended elements of notebooks and tablets.

“It’s a new pocketable Surface device form factor that brings together innovative new hardware and software experiences to create a truly personal and versatile computing experience,” the Microsoft document says, according to the Verge report by Tom Warren, who says this earlier concept art by David Breyer is on the mark with the latest prototypes.

Code-named Andromeda, the device has been the subject of widespread speculation in recent months amid a series of leaks and clues in the Windows APIs and other code, including this new tidbit appearing to reference the different states of the device hinge.
